We present 2 cases of retropharyngeal abscess in adults as complication of acute tonsillitis and cervical pyogenic osteomyelitis, respectively. These cases confirm that retropharyngeal abscess has a significant morbi-mortality despite of new antibiotic drugs introduced. A review of the present characteristics of the complaint is treated in this paper.
Reporting one case of pseudocyst of the auricle in a young male, 18, white and wealthy, diagnosed and treated. Bibliographical review of this condition and explanation of its etiopathogenetic, clinic and therapeutical characteristics, as well. This deformity seems to be more prevalent as the number of published cases may suggest.
Peripheral facial paralysis from tumoral origin is scarce in number, in spite of possible manifold causative growths. One case in which the palsy was associated to a rhinopharyngeal neoplasm is reported and possible ways of nerve involvement discussed. Although progression seems to be the most probable hypothesis in this instance, only the anatomo-pathological exam has affirmative value.
The Electroneurography (ENoG) is one of the most employed electrodiagnostical techniques in the appraisal of acute facial palsies (AFP). Since 1989 we have to resort systematically to this exploration in our ENT-Department, which task previously was province of the Neurophysiological Service. On accordance with the exam's results we then express the prognostic, regarding the seriousness of the paralysis, and so settle the indication or the abstention for the rehabilitative treatment. We report here a review of 92 APF's seen during 1990 and consider their evolutive course which is compared with that in advance supposed to be. In the light of our final results we venture to say that ENoG, in our hands, is a good prognostical indicator and also is an adequate standard of judgement in order to recommend the rehabilitative management of AFP.
A 43-year-old female patient complaining with odynophagy since a month and a half without response to the medical treatment is presented. The pharynx exam showed an asymmetric swelling in the right tonsillar surface and the radiology provided evidence of calcareous concretions as responsible cause of the picture.
Facial nerve neurinomas are unusual tumors which originate fin the Schwann cells of the nerve sheath. Diagnosis of these tumors has improved in the last years due to radiological and clinical advances. Here presented is a case study of a patient with neurinoma of the primary facial nerve which clinically manifested itself as a recurrent facial paralysis. A high resolution T-C scan was sufficient for tumour identification, treatment consisted in a middle fossa approach and tumour removal followed by hypoglossa-facial anastomosis.
A 43 year-old man with a cystic mass on the side of the neck was admitted to the hospital for possible branchial cyst. The histopathological analysis showed a carcinoma developed on a branchial cyst. After reviewing the literature, we conclude that carcinoma developing on a branchial cyst is uncommon, if, indeed, it exists at all. The diagnostic criteria should be adhered to strictly. When confronted with this histopathologic diagnosis, the possibility of cystic metastasis to the neck of a squamous carcinoma of unknown origin should be considered.
